Delegate Robert Costa, a Republican from Anne Arundel County, has also said he will support the bill.

He voted for the bill earlier this week in committee.

House Minority Leader Tony O'Donnell told WBAL News that he was not concerned that two members of the 43 member House Republican caucus were voting for the bill. He noted the opposition to same sex marriage is bi-partisan.

One Democrat, who was considered undecided, told WBAL News today that she will vote for the bill.

Democrat Pam Beidle, whose district includes Glen Burnie, said she is voting for the bill, but she believes that it should be put to voters in a referendum.

Beidle said that she has been flooded with phone calls and emails, and she even conducted an online poll on her website.

Beidle said that of the people from her district, she found 54% favored same sex marriage.

Another Democrat, John Olszewski of Baltimore County said that he would support the bill.

The Dundalk area lawmaker, who chairs the Baltimore County House Delegation, said he was concerned about religious protections in the bill.

He says those are adequate.

Under the bill, clergy would not be forced to perform same sex marriages, and religious facilities would not be forced to host same sex wedding ceremonies or receptions.

Lawmaker: O'Malley Apologizes For Wife's Remarks

Before delegates returned to the House floor Thursday evening, Governor Martin O'Malley apparently apologized for remarks his wife made last month calling lawmakers who voted against same sex marriage last year "cowards."

Baltimore County Democratic Delegate Emmett Burns, who opposes same sex marriage, attended the meeting and confirmed the account to WBAL News.

"His head was hung low. He wanted sympathy, and it was a big thing for him to do," Burns told WBAL News after Thursday night's House session.

Katie O'Malley apologized one day after making the remarks last month at a conference of lesbian, gay, bi-sexual and transgendered activists.

A top aide to the governor did not confirm Burns' account, but he did confirm the governor's meeting with lawmakers.

"The governor met with the Democratic caucus and thanked them for their efforts in debating this important issue," O'Malley aide Rick Abbruzzese told WBAL News.

Aides to Speaker Michael Busch also confirmed the governor met with the Democratic Caucus, but would not comment on Burns' remarks.
